example 1
3-[1-(5-Phenylethynyl-pyridine-3-carbonyl)-piperidin-4-yl]-benzylamine di-hydrochloride (A.K.A. [4-(3-Aminomethyl-phenyl)-piperidin-1-yl]-(5-phenylethynyl-pyridin-3-yl)-methanone) di-hydrochloride)
A. B-{3-[N,N-bis-(tert-butoxycarbonyl)aminomethyl]-phenyl}-pinacolato-boron
[0240]A solution of 3-bromobenzylbromide (7.5 g, 30 mmol) and di-tert-butyliminodicarboxylate (6.5 g, 30 mmol) in anhydrous tetrahydrofuran (80 ml) was treated portionwise with sodium hydride (1.2 g, 60% dispersion in mineral oil). After stirring at ambient temperature for 7 hours the reaction mixture was partitioned between saturated aqueous ammonium chloride solution (90 ml) and ethyl acetate (2 lots of 250 ml). The combined organic layers were washed with brine (75 ml ), then dried over magnesium sulfate and then concentrated under vacuum. The residue was subjected to chromatography on silica gel eluting with a mixture of pentane and dichloromethane (2:1, v / v) to give 3-[N,N-bis-(tert-butoxycarbonyl)aminomethyl]-...
example 2
3-[1-(5-Phenylethyl-pyridine-3-carbonyl)-piperidin-4-yl]-benzylamine di-hydrochloride (A.K.A. [4-(3-Aminomethyl-phenyl)-piperidin-1-yl]-(5-phenethyl-pyridin-3-yl)-methanone di-hydrochloride)
A. 5-Phenylethyl-pyridine-3-carboxylic acid
[0244]A solution of 5-phenylethynyl-pyridine-3-carboxylic acid (2 g, 8.9 mmol) in tetrahydrofuran (50 ml) was treated with 10% palladium on carbon (200 mg) and stirred at ambient temperature under an atmosphere of hydrogen for 5 hours. The reaction mixture was filtered through a short pad of hyflo and the filtrate was concentrated under vacuum to give 5-phenylethyl-pyridine-3-carboxylic acid as white solid (2 g). 1H NMR [(CD3)2SO, 500 MHz]: δ 8.90 (m, 1H), 8.60 (m, 1H), 8.12 (m, 1H), 7.21 (m, 5H), 3.38 (br s, 1H), 2.95 (m, 4H).
B. N,N-Bis-(tert-butoxycarbonyl)-3-[1-(5-phenylethyl-pyridine-3-carbonyl)-piperidin-4-yl]-benzylamine
[0245]By proceeding in a similar manner to the method described in EXAMPLE 1C, but using of 5-phenylethyl-pyridine-3-carboxylic ac...
example 3
3-[1-(1-oxy-5-phenylethyl-pyridine-3-carbonyl)-piperidin-4-yl]-benzylamine hydrochloride (A.K.A. [4-(3-Aminomethyl-phenyl)-piperidin-1-yl]-(1-oxy-5-phenethyl-pyridin-3-yl)-methanone hydrochloride)
[0247]A solution of N,N-Bis-(tert-butoxycarbonyl)-3-[1-(5-phenylethyl-pyridine-3-carbonyl)-piperidin-4-yl]-benzylamine (100 mg, 0.17 mmol, EXAMPLE 2B) in dichloromethane (10 ml) was treated with meta-chloroperbenzoic acid (80%, 80 mg, 0.37 mmol). After stirring for 18 hours at ambient temperature the reaction mixture was diluted with dichloromethane (40 ml) and then washed three times with saturated aqueous sodium bicarbonate solution (20 ml). The organic phase was dried over magnesium sulfate and then concentrated under vacuum. The residue was subjected to chromatography on silica gel eluting with a mixture of dichloromethane and methanol (98:2, v / v) to give N,N-bis-(tert-butoxycrbonyl)-3-[1-(1-oxy-5-phenylethyl-pyridine-3-carbonyl)-piperidin-4-yl]-benzylamine as a colorless oil (70 mg).
